To all who-m it may concern.-

Be it known that I, DEWITT W. STRIQK- LAND, a citizen of the United States, residing at Tylertown, in the county of VValthall and State of Mississi pi, have inventedcertain new and useful mprovements in Trig be means to prevent the trigger shiftingA after it has beenv set to one side and before it has fired the gun and also .in which there will be means for normally holding the trigger in a central or neutral position. Other objects ofthe invention will appear in the vcourse of the following description. The invention resides in certain novel v features which will. be particularlypointed out in the appended claims..

In the drawing Figure l 'is a view partly in side elevation and partly in longitudinal section of a portion of a gun having my improved trigger appliedthereto; f A

the arrow;

Fig. 3 is a transverse section on the line 3 3 of Fig. 1 lookingin the direction indicated bythe arrows;

Figs. 4 and 5 are transverse sections ap` pro`ximately` in the plane in which Fig. 2 is taken but looking in the opposite direction and showing di t`ferent .positions of the trig-v ger;

trigger plate with vthe trigger Amounted thereon andthe parts coperating with thel The gun may beof any well-known type, Fig. 1 showing a portion ofa well-known form of so-called hammerless gun and in said figure. the reference numeral l designates' the trigger plate,.2 -the guard around Fig. 6 is a detail perspective viewiof the' the trigger, 3 the trigger,and 4 one'of the barrels, 5 being the hammer controlled .by the Sear 6. A sear and hammer 5 are provided for each barrel'andthe sears are disposed immediately adjacent 4the Side Walls of the lframe-'of the gun and are equipped at their rear ends withinwardly projecting lateral branches 7 which are adapted to be engaged by the trigger inthe firing operationv and thereby moved upwardly against the tension of the spring 8 which also acts upon the hammer 5 so that, when'the sea'rfis released, the hammer will be at once thrown against the firing pin and the gun fired. The trigger `3 is' pivotally mounted within the, frame of the gun in the usual manner and in its upper portion adjacent its rear end is constructed with a transverse notch 9v in whichis pivotally mounted a post lO for rockmg movement transversely of the trigger, The. upperend of this post is bifurcated, las indicated at 11, and in the bifurcationis mounted a roller 12 which iS adapted to impinge against the branches 7 of the sears, as shown clearlyin Figs. 2, 4

and 5, to release the sears,'the roller reducing the frictional wear caused by the engage ment of the parts in firing the gun, The lower end .of the post 10 is flat, asshown clearly in Figs. 2, 4 ando, and in the ltrigger immediately-below the post is a vertical chamber'l to accommodate a spring 14 coiled around a plunger 15 Slidably fitted in the trigger and provided with a head 16 held against the bottom of the post 10 .by the spring. The plunger 15 is mounted inthe central longitudinal plane of the trigger and by its pressure 'upon the rocking post, 10 tends to hold said post inthe verticalplane of the trigger and, therefore, in neutralvpo sition. AS a result of this tendency of the post to remain in the neutral position it will be automatically returned to said position as it is vretracted after firing either barrel and will be, therefore, in position to engage lthe fly or Shipper to--be properly shifted when (the `gun is again fired. The pivot' 17 of the post 10 projects beyond' the rear endof' the trigger in .position to be engaged by the trigger'spring .1S-so thaty the trigger will b e normally `held projected from the frame of the gun, or in its lowered position, and in the upper side ofthe trigger immediately in rear o -f the rocking post 110 is a Vlshaped notch 19 tofaccommodate a projection :200m 'the rearsideof the rocking post.` This pro ,s arily` limiting the Y lateral movement of lthe rocking posit. n It will also be readily under=4 'stood v'u'pon reference to Fig. 3 that theilower end of this projection is adapted to engage the side Walls of the notchl 19 limit the lateral movement ofthe rocking post so that' itlcannot be carried beyondthe 'point' VWhere it will vupon the front 'side'.of afpost 22, rising from the trigger plate 41` in 'rear'ofj the trigger, the' pivot for' the fily'consisting of headed srew or pin 23, the'head ofivhich Vretains the fly upon tje' post 22. In, its upper side, thejfly-isprovided fivitli notches 24 disposed at" opposite sides of itscenter andjthese notches'are adapted to be engaged vby aholding'y 'springv 25secured` vupon the.' postk 2 2 Land projecting over thev "It will .be readily understood Ithfatbjy engaging either Yof the notches '2e 4thfes'j'q'ring holds the `fly in the position in -`'which under side ofthe" fly anddiainetrically 9ppositie'v theridge separating the notches24f i'sla'tooth26having beveled sides and at the jill'rfietifon of said' sides with Athe, peripheral -s'urface'o'fi'thelfly are grooves or notches 27.

To this end, a depending lug or arm 28 is provided on the under side' of the fly in. rear of the tooth 26' andyin alinement therewith. Athe gun l secu/re sleeves or casings 3Of'inA which are housedl springsl and` through which are slidably -fitted plungers 32,"the springs'serving-to hold 'the plungers nor-A mally in their outer' positions.

yThe operation of thejdeviceis thought to be evident from the descriptionhereinbefore giv'enand-it will be 'noted'that the deviceis exceedingly simple in construction andlcompactly arranged.- It will be positive in' its action so thatthe barrelsl of the gun will be fired alternately and it Willobviousl'y 'operate as fast as the trigger can be actuated toirethegun.- Y D Having thus described the invention, what is claimed as new is:

l. In a double-barrel gun, the'combination of a trigger mounted for vertical movement,

a-rocking post carried by said trigger, means forv shifting said post laterally'as .the 'trigger lis raised', and a spring-controlled' plunl ger mounted in the trimrer and'bearing upon the lower' end of the post to holdy it normally in central vertical position.; 2. ln 'a` double-barrel gun, the combina]-l tion ofia trigger mountedfor `vertical movebe successivelyshifted, anclfyieldable`means ment, a rocking post carried by said trigger' for engaging the,v fly and holding it a' set of a' trigger having a notch in its rear end,

a rocking post carried by the trigger and having a projection playing in and engaging the Walls of said notch to limit the lateral movement of the post, means for shifting the post laterally as the triggeris raised, and means for returning the post to itsl neutral position as the ltrigger is lowered.

4. In a double-barrel gun, the combination of a trigger, a rocking post carried by thg trigger, a' fly pivotally mounted in rear 051 the rocking post and above the trigger, said fly being provided in its upper edgewith spaced grooves, a spring latch mounted on a fixed support adjacent the fly and selectively engaging said'grooves to hold the fly in a set position, and ooperating means on the rock'- ing post and the y to shift the postlaterally to fire one barrel ofthe gun.
